OF NEW YUP-iii, L, ASSIG-NOR "F30 SEE-GAL Application filed November 30,1'52 To all whom it may concern:

Be it known that I, SAMUEL Susan, a citizen of the United States, and aresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Epring Pins, ofwhich the following is a specification.

My invention relates to hardware and in its specific embodiment itrelates more particularly to locks although in its application it is notso limited.

The invention has for its object the production of a novel, simple andinexpensive spring pin adapted to be mounted in an opening in a wall andcapable of transverse movement in said opening.

In the embodiment of the invention illustrated in the accompanyingdrawing the invention is shown in the form of a spring pin mounted in anopening in the wall of a lock casing and adapted to act as a detent orstop to prevent movement of the latch bolt within the lock casing.

lily invention consists in the details of construction and combinationsof parts hereinafter more particularly described and then specified inthe claims.

In the accompanying drawing:

Fig. 1 is a front elevation of a lock casing showing my inventionapplied thereto.

Fig. 2 is a plan view thereof, partly broken away.

Fig. 3 is a horizontal section on the line 33 of Fig. 2.

Fig. a is a front elevation of pin.

Fig. 45 is a side elevation thereof showing the spring wire of the pinbefore it has been bent downwardly into proper position.

Fig. 5 is a front elevation of a modified form.

Fig. 6 is a horizontal section on the line 66 of Fig. 5.

Fig. 7 is a modification.

Fig. 8 is a horizontal section on the line 8-8 of Fig. 7.

Referring in detail to the several figures of the drawing:

through an opening in the side wall thereof, as shown in Fig. 2, andprovided with a shoulder 55. The parts just described are old in the artand their construction is well understood so that they require nodetailed description. 6 indicates an annular opening extending throughthe wall 3 of said casing and 7 indicates a ring or reinforced portionadja- CQIL 1 Perv. o -b salu opening i. nci 1s pieioiao y integral withsaid wall whereby a wall of in creased thickness and strength isprovided this point.

8 indicates the head of a pin having a cylindrical shank 3 of a sizepermitting it to slidably interfit with the opening 6 in the wall 3.{laid shank of said pin is provided with opposite flattened sides 10, asillustrated, whereby a space obtains intermediate said flattened sidesand the wall. of the annular opening 6 when the pin is mounted in saidopening. Said shank is perforated as at 11 and is adapted to receive aspring wire 12.

For mounting the pin in the annular opening 6 the spring wire is firstinserted in the oration 11 in the shank 9 as shown in The ends of thewire are then bent ownward adjacent the flattened sides 10 of the sha ndthe shanlr carrying the wire is inserted in the annular ope ing. The pinis then pressed forwardly whereby the head 8 thereof will seat againstthe ring 7., said head 8 providing a stop to lirni the forward. movementof said pin. The end of the shank 9 is then hammered to offset the sameand provide flange 13 (see Fig. 4:) acting as a stop to preventwitl'idrawal of the pin from the opening.

YVhen the pin is thus mounted in proper position the ends of the springwire 12 lie in the spaces intermediate the flattened sides 10 and thewall of the opening 6 and the spring action in said wire tends to flarethe ends thereof outwardly whereby said wire will at all times engagethe wall of the opening 6. The frictional resistance provided by thisengagement prevents the pin from working loose within the opening andretains it in forward, intermediate or rear position, as desired, untilit is manually changed to different position, the head 8 providing aconvenient gripping means for operating said pin. The engagement of thespring wire 1:2 with the wall of the opening 6 prevents the withdrawalof the spring wire from the perforation 11 as is obvious.

the previous case.

In the modification illustrated in Figs. 5 and 6, the shank of the pinis provided with but one flattened side indicated at 1 1 and theperforation in said shank which is indicated at 15 is adjacent theforward end of said shank instead of adjacent the rear end or operatingknob as in the preferred form of the invention. Said perforation isclosed in any desirable manner at the rounded side of the shank and oneend of a spring wire 16 is inserted in said perforation and the springwire bent over towards the flattened side as indicated, after which thepin carrying said spring wire is inserted and mounted in the annularopening in the wall of the casing as in the previous case.

In the modification illustrated in Figs. 7 and 8 the shank is providedwith a groove or-slot- 17 and with a perforation 18 registering withsaid groove or slot and extending through said shank and closed at theend remote from said groove. One end of a spring wire 19 is insertedwithin said perforation and the wire is then bent over whereby it enterssaid groove or slot. The pin is then inserted and mounted in the annularopening in the wall of the casing as in In all the forms shown anddescribed, when the latch bolt 4 is in retracted position within thelock casing, it may be positively held in this position against theaction of its spring by merely pressing the head 8 of the pin, wherebythe end of the shank thereof will be brought within the casing for e11-gagement with the shoulder 5 on said latch bolt to prevent movementthereofin an ob vious manner.

It will be apparent that my improved de ing therein, of a pin providedwith a per-. foration and a spring wire loosely extending in saidperforation in a direction transverse to the direction of said pin'andbent over and engaging the wall of said opening.

2. In a device of the character described, the combination with a wallhaving an opening therein, of a pin provided with a shank having aperforation, a head on one end of said shank and a stop on' the otherend whereby withdrawal of said pin from said opening is prevented and aspring wire extending in said perforation in a direction transverse tothe direction'of said shank and bent over adjacent said shank and engaging the wall of said opening.

3. In a device of the character described, the combination with a wallhaving an annular opening therein, of a cylindrical pin having aflattened side and a perforation in said flattened side and a springwire extending in said perforation and bent overadjacent said flattenedside and engaging the wall of said opening.

4.. In a device of the character described,

the combination with a wall having an annular opening therein, of acylindrical pin having opposite flattened sides and a perforation and aspring wire extending trans versely through said perforation and havingthe ends thereof bent over adjacent said flattened sides and engagingthe wall of said 7 opening.

5. In a lock, the combination with a casing having an opening in. a wallthereof, a bolt mounted in said casing, a pin extending through saidopening and adapted to engage said bolt and provided with a perforationtherein and a spring wire extending in said perforation in a directiontransverse to the direction of said shank and bent over adjacent saidshank and engaging the wall of said opening.
